Would you add total strangers on Facebook?

I did a post a while ago on my facebook page saying that I won't accept friend requests from people who are either total strangers or people from high school that I didn't get along with, but I'm partially going against my word and I added someone that I have never met in my life. The reason I added her was because we're both members of a dating/friends group on facebook and I figured that I would give this person a chance, I guess. I hope I don't regret this decision later on. Making new friends on facebook couldn't hurt, right? Have any of you out there ever have any good or bad experiences with adding strangers to your facebook friends list? Did I make a bad decision?
